To find the model number on Nike shoes , you can check the tag or label inside the shoe . It is usually located on the tongue , collar , or heel of the shoe .

Locate the tag inside your shoe. All authentic Nike shoes have a tag sewn into them with their size, barcode and model number on it. You will recognize it most easily by the barcode.

Every pair of authentic Nike shoes comes with an SKU number that is identical to the SKU number on their box. If the numbers are missing or do not match, they are likely fakes. Check the tongue label. Often, fake Nike manufacturers put outdated sizing labels on the inside of the shoe.

Like many other manufacturers that sell directly to consumers online, Nike is not interested in authorizing retailers to sell its products on the internet. Authorized Nike retailers are not authorized by the company to sell its products on their websites.
